Yeah I really need to get bank 1 seals replaced. If I swap those and still have a problem I'm out of ideas other than an issue with the heads themselves. PCV system is gone now and I'm still getting lots of smoke after it idles for a minute or two, so I think that wasn't the problem.
Anyway, if the bank 1 seals don't fix it I'm gonna see if TSP will exchange the heads for me.

I can't just take the motor back. I had a machinist build the shortblock, but I did final assembly on heads and everything else. I called him and asked, and he said he couldn't see the pistons and rings being a problem.

shouldnt have anything to do with it.. the pressures from a restricted exhaust is nothing compared to the pressures your rings see when they are on the compression stroke. if compression test checks out then your probably not pushing pressure into the crankcase.
if the PCV is deleted you will no longer have positive crankcrase ventilation though... the pressure will push itself out of the breathers as it builds up.
